Problem is fixed, now compilation succeeded. u-boot.bin has size 243788
bytes.

And seems that compiled U-Boot is working fine!

Nokia RX-51 # version
U-Boot 2021.04-rc3-00338-g88d0a5042c97 (Mar 06 2021 - 22:19:08 +0100)

arm-linux-gnueabi-gcc (Debian 8.3.0-2) 8.3.0
GNU ld (GNU Binutils for Debian) 2.31.1

I can send binary files via usbtty and 'loadb' command. I can boot linux
kernel via 'bootm'. I can chainload to another U-Boot binary (loaded by
'loadb') via 'go' command. Also 'ext4ls' and 'fatls' commands are
working. Also 'onenand dump bootloader' is working.

Do you need something more to test?

If not you can add my 'Tested-by: Pali Roh?r <pali@kernel.org>' line for
all patches which are up to the commit 88d0a5042c97.

Good job!
